Item Chest Wall Implantation Metastasis Caused by Percutaneous Radiofrequency Ablation for Hepatic Tumor(2015) Kilic, Dalokay; Uysal, Cagri; Akdur, Aydincan; Kayipmaz, Cagri; Tepeoglu, Merih; Boyvat, Fatih; 0000-0002-9894-8005; 0000-0002-8726-3369; 0000-0001-6236-0050; 25742838; H-7700-2019; F-4230-2011; AAK-5222-2021; AAA-3068-2021We report a very rare case of a 55-year-old man with chest wall metastatic tumor caused by seeding of hepatocellular carcinoma after percutaneous radiofrequency ablation (RFA) for hepatic tumor 42 months after the initial operation. The patient was managed with aggressive full-thickness chest wall resection and reconstruction with a Prolene (Ethicon, Somerville, NJ) and methyl methacrylate sandwich graft and subsequent musculocutaneous free-flap transposition.

Opportunistic pulmonary infections frequently occur after liver transplantation, and affect mortality and morbidity significantly. The purpose of this study was to define the incidence, types, and imaging characteristics of pulmonary infections in liver transplant recipients with multidetector CT (MD CT) evaluation. Methods. Thirty-five adult transplant recipients diagnosed with a pulmonary infection within the first 45 days posttransplantation were reviewed retrospectively from March 2002 to December 2013. MDCT features were evaluated retrospectively by 2 radiologists in consensus. All diagnoses were made by sputum analysis, cultures, biopsies, and postmortem histopathologic evaluation. Results. Pneumococcus pneumonia was found in 7 patients. Five patients had nonspecific pneumonia, Candidiasis, Klebsiella, and Aspergillosis separately. S aureus pneumonia was detected in 2 patients and the other 2 patients had Escherichia coli pneumonia. Two patients had active tuberculosis and 1 patient had Acinetobacter pneumonia also. Four main MDCT patterns were identified: patchy infiltrations (10%), tree-in-bud pattern (9.5%), ground-glass opacity (8.5%), and nodules with halo sign (6%). One patient had a cavitary lesion owing to tuberculosis. Conclusion. Although the incidence of pulmonary complications in liver recipients was relatively low, mortality from serious infections was high. Care must be taken with pulmonary infectious complications in the posttransplant period. For any suspicious case, MDCT evaluation for specific patterns of early accurate diagnosis is very important.Item Effect of Nasal Packs in Septoplasty(2015) Eski, Erkan; Yilmaz, Ismail; 0000-0002-4784-3342; 0000-0002-1694-7608; 26052044; AAD-5458-2021; AAJ-2992-2021Item Risk Factors and Treatment Options for Persistent Hyperparathyroidism After Kidney Transplantation(2020) Kirnap, Nazli Gulsoy; Kirnap, Mahir; Sayin, Burak; Akdur, Aydincan; Tutuncu, Neslihan Bascil; Haberal, Mehmet; 0000-0002-8726-3369; 0000-0002-3462-7632; 0000-0002-1816-3903; 0000-0001-8287-6572; 31924405; AAA-3068-2021; AAJ-8097-2021; ABG-5027-2020; J-3707-2015Background. Kidney transplantation (KT) corrects secondary hyperparathyroidism. However, persistent hyperparathyroidism (pHPT) may be observed in some patients post-KT. This study aims to evaluate the risk factors and treatment options for pHPT. Materials and methods. The study population comprises 1054 patients who underwent KT between January 2001 and May 2019. Serum samples were analyzed for calcium (Ca), phosphorus, creatinine, intact parathyroid hormone (iPTH) and estimated glomerular filtration rate. Results. The prevalence of pHPT following KT is 14%. Ninety pHPT patients were compared with 550 non-pHPT patients. The median duration of pre-KT dialysis was longer, and pre-KT serum Ca, P, and iPTH levels were significantly higher in the pHPT group than the non-HPT group. The pHPT of 46 patients (51%) received medical treatment. The remaining 44 patients (49%) had parathyroidectomy (PTx) if symptoms or signs (or both) of pHPT continued. Subtotal PTx was performed in 35 patients, and minimally invasive PTx was performed in 9 patients. Conclusion. Based on our study results, the most important risk factors for post-KT pHPT are long dialysis duration and high pre-KT iPTH levels. In patients who underwent KT, if pHPT lasts longer than 1 year, surgical treatment is the recommended approach. Based on our experience, the treatment method to be performed in pHPT should be 3+1/2 PTx.Item Lacrimal dilator-facilitated incisionless vs. standard sub-Tenon's block: a randomized, prospective and non-inferiority comparative study(2020) Coban-Karatas, Muge; Cok, Oya Yalcin; Kumar, Chandra M; 0000-0003-3004-2626; 33005046; AAI-7998-2021Background/objectives Standard sub-Tenon's block (STB) involves incision (dissection) of conjunctiva and Tenon's capsule with the help of blunt scissors and forceps, insertion of a blunt sub-Tenon's cannula under the Tenon's capsule and injection of local anaesthetic agent. STB is frequently associated with minor complications such as chemosis and postoperative subconjunctival haemorrhage but rare sight and life-threatening complications. To reduce these minor complications, several variations of incisionless STB have been described however, there are no comparative data. One such incisionless STB involves the use of lacrimal dilator which is easily available in the operating theatre. We compared incisionless lacrimal dilator-facilitated with the standard STB for effectiveness, chemosis, and postoperative subconjunctival haemorrhage. Subjects/methods After obtaining ethical approval, patients scheduled to undergo elective phacoemulsification cataract surgery were enroled to receive incisionless lacrimal dilator-facilitated STB (Group LD) or a standard STB using Wescott scissors and blunt forceps (Group WS). All patients received 3 mL 2% lidocaine without any adjuvant. No sedation was administered. Demographics of the patients, duration of the procedure, analgesia, akinesia, duration of the procedure intraoperative chemosis, and postoperative subconjunctival haemorrhage were compared. Results Both groups were comparable for demographic data, duration of the procedure, analgesia, and akinesia (p > 0.05). The severity of chemosis and postoperative subconjunctival haemorrhage were significantly lower in Group LD (n = 32) in comparison to Group WS (n = 31) (p < 0.001). Conclusions Incisionless lacrimal dilator-facilitated STB decreases intraoperative chemosis and postoperative conjunctival haemorrhage in comparison to standard STB. Analgesia and akinesia are comparable in both techniques.
